Video filmed at Heathrow airport shows planes visibly shaken by high-speed winds as they attempt to land.

In one clip shared on social media, a British Airways aircraft approaches the runway but is forced to perform a “go-around” – increasing altitude in order to make a second landing attempt – after being battered by winds that see it sway dramatically from side to side.

“New pants please!” reads the video caption on Twitter, accompanying footage taken by Big Jet TV’s live stream from the airport.

The scale of the problems facing train operators and Network Rail as Storm Eunice causes travel havoc is shown in a list produced by South Western Railway. It shows no fewer than 16 fallen trees in the network.

BA, which has so far cancelled more than 120 flights as Storm Eunice takes hold, has updated its message to passengers.

It reads: “Due to the extreme weather conditions across the UK and resulting restrictions on the number of aircraft that can take-off and land each hour, we, like other airlines, are experiencing significant disruption.

“We’re operating as many flights as we can and putting on larger aircraft where possible. Customers due to travel on a short-haul service today can rebook for free on ba.com.

“Those whose flights have been cancelled are being contacted to offer options including a full refund.

“Safety is always our priority and we’re encouraging customers to check the latest flight information on ba.com before heading to the airport.”

A flight operated by Norwegian appears to be returning to Helsinki after making two attempts at landing at London Gatwick. Flight D82766 from the Finnish capital had made the 1,150-mile trip to the Sussex airport. But after two rejected touchdowns due to high winds the Boeing 737 appears to be returning to Heathrow.

An inbound British Airways flight from Istanbul to Heathrow diverted to Stansted after a “go-around” at the west London airport.

The early Royal Jordanian flight from Amman to London Heathrow diverted to Athens. It is not clear when it might continue its journey.

British Airways has now cancelled more than120 flights as a result of the severe winds brought by Storm Eunice.

A large majority are to and from London Heathrow airport. All storm-related cancellations so far are for domestic and European links.

“New” cancellations announced on the day include links to Oslo, Nice and Moscow.

BA is telling passengers: “If your short-haul flight is still operating on 18 February 2022 and you wish to change travel dates, you can do so for free up to and including 21 February 2022, by visiting Manage My Booking.

“If your flight has been cancelled, you can visit Manage My Booking to view rebooking or refund options.”

Passengers whose flights are cancelled are entitled to be flown to their destination as soon as possible, even if it means British Airways buying a flight on another airline.

No trains are running between one of London’s leading rail hubs, Liverpool Street, and Hackney Downs. “All lines are blocked,” reports National Rail. “Trains running between stations may be cancelled or delayed. Disruption is expected until 11am.”

A tree is blocking the railway at Overton in Hampshire. “Trains between Salisbury and Basingstoke may be cancelled, delayed or revised,” says National Rail. “This is expected until 12 noon”. Journeys on South Western Railway to and from London Waterloo are affected.

Northwest of the capital, a tree has fallen on the Chiltern line between Amersham and Great Missenden, halting trains.

Almost all train operators are warning against travel on Friday.

The Met Office has taken the unusual step of issuing a severe weather alert with National Highways for strong winds covering the whole of the country’s strategic road network – which includes all motorways and some A roads – from 6am to 6pm.

High-sided vehicles and other “vulnerable” vehicles such as caravans and motorbikes could be blown over so should avoid bridges and viaducts, National Highways said.

National Highways head of road safety Jeremy Phillips urged those travelling to “plan your trip and take extra care, allowing more time for your journey”, adding: “In high winds, there’s a particular risk to lorries, caravans and motorbikes so we’d advise drivers of these vehicles to slow down.”

“Drivers of other vehicles should be aware of sudden gusts of wind which can affect handling and braking, and give high-sided vehicles, caravans, and motorbikes plenty of space. In the event of persistent high winds we may need to close bridges to traffic for a period, so please be alert for warnings of closures and follow signed diversion routes,” he added.

Transport for London (TfL) has issued a Red Weather Warning and advised passengers not to travel today.

In an email to customers, TfL wrote: “Due to the Met Office’s red warning over Storm Eunice, customers are advised to only travel if essential.

“We are doing all we can to ensure we are prepared for any impact with extra staff ready to respond quickly to any incidents but some services will be affected by the extreme weather.

“Check before you travel or our TfL Go app can help you plan your journey.

“Please take care if you travel.”

Passengers at Paddington station, the London hub for GWR trains to the West of England, South Wales and the Cotswolds, are finding that around three-quarters of trains are being cancelled.

With all train services in Wales already cancelled for Friday, it was known that services would go no further west than Bristol. But since the start of the day, dozens more trains – including many serving Heathrow airport – have been axed.

GWR is trying to run an hourly service between Bristol Temple Meads and London Paddington, with connecting services to Oxford and Cheltenham Spa.

The train operator said: “We are advising customers not to travel unless their journey is absolutely essential.

“The priority will be to keep trains running and customers moving safely where we can, but we have had to make significant changes to our services across the network to allow that to happen.”

Rail services nationwide will be disrupted by Storm Eunice today, as the country sees winds of up to 100mph in some parts. All train services are cancelled in Wales for the remainder of the day.

Many train operators are recommending that you do not travel today unless you absolutely have to.

At London St Pancras, the 08:18, 08:47 and 09:15 to Corby are all cancelled; as are the 08:25 to Ramsgate, the 08:30, 09:00 and 09:10 to Bedford and the 08:35 to Nottingham.

The 08:55 to Faversham and 09:02 to Sheffield are both cancelled.
